A doctor may suggest IV access through a bigger vein via a central line or peripherally inserted central catheter (PICC) line. This is because the needle can easily become displaced from the vein. Getting them through a vein is helpful when you can’t take medications by mouth or you need the medications to work quickly.īutterfly needles usually aren’t a long-term solution to IV therapy, such as giving medications or fluids.

The needle has flexible tubing attached to the end that makes it easy to connect to other tubing to collect blood. The smaller-length needle is easier to place more precisely on veins that are especially fragile, small in size, or that roll.īutterfly needles are often used when a person is giving blood, such as for a blood bank. The butterfly needle requires a shallower angle compared to an IV catheter.

A phlebotomist is a medical professional who specializes in drawing blood.īutterfly needles are often used on people who might be difficult to perform venipuncture on. Drawing blood is one of these cases.Ī person drawing blood may choose a butterfly needle when drawing blood for the following purposes: VenipunctureĪ venipuncture is when a phlebotomist accesses a vein to draw blood. There are certain cases where one should be chosen over the other. However, the butterfly needle is usually smaller in length than an IV catheter. This is different from a butterfly needle, where the needle gets left in the vein instead of a plastic sheath.
